Hey, I noticed that too after the last app update.
This is the relevant change that leads to the problem: #3154
I was able to solve it by manually changing the php line back.

Maybe someone with background knowledge can explain this and/or start a new backport.
I don't know where the "mobile_editing" config variable has to be entered.

Best regards

Thanks for reporting, just pushed a fix for this in #3184

[Mornsgrans]

I tried setting the "mobile_setting" config in my confuguration using the occ-command as mentioned in #3184 and it made the bahavior worse.

Independent of the value "yes" or "no" even in the Firefox browser always my local Libreoffice will be executed after click on the office document instead of opening in Nextcloud office. Opening documents in Nextcloud office on PC in the browser only works, if the entry "richdocuments mobile_editing" does not exist.

The issue still persists, now with
Collabora Online - Built-in CODE Server 23.5.402
and
Nextcloud Office 7.1.6
There still the document becomes downloaded and I am asked to select an Android app to open it.
In my Browser under Windows it works.

Edit:
With Collabore Online - Built-in CODE Server 23.5.503
and
Nextcloud Office 7.1.8
it works now. - Thank you.
